Note: Price is for one motor Features: 1106 3500kv custom brushless motor 2s-4s rated voltage 16mm, 28.5:1 or 10 all metal planetary gearbox 3mm or 4mm "D" extra long output shaft (can be cut to length) 28.5:1 Drive with 3mm shaft - 23.9g 28.5:1 Drive with 4mm shaft - 24.7g 107:1 HR with 3mm shaft - 27.3g 107:1 HR with 4mm shaft - 28.3g ~23g weight with 3mm shaft (can lower the weight by cutting down the shaft and shortening the wires) ~24g weight with 4mm shaft (can lower the weight by cutting down the shaft and shortening the wires) ~28mm body length for Drive ratio ~31mm body length for HR ratio 10.5mm M2 Face mount hole pattern Comes ready for combat, just solder the motor leads to a brushless ESC and you're on your way (Soldering iron required) Find the 3D Model here: https://grabcad.com/library/repeat-mini-mk4-1 Improvements vs Mk3 design: 1204 was changed to a 1106 for more stator volume and more outrunner clearance Output shaft is made from hardened 4130 steel, to improve lifetime and is integrated into the carrier plate, to improve durability. Output shaft is retained without the use of a circlip, eliminating the main failure mode and improving the durability Further changed the wire retention with stronger stator winding wires and mechanical clamping of the wires at the stator base. Gearbox baseplate is integrated into the brushless motor base, removing screws and additional points of failure. Disclaimers: These gearboxes can only accept ~2mm of face screw engagement. Using screws that are too long will result in damage.
